Abstract

We propose a new geometry for nanogap electrochemical sensing devices. These devices consist of two closelyspaced side-by-side electrodes which work under redox cycling conditions. Usingfinite element simulations,we investigate the effects of different geometric parameters on the redox cycling signal amplification to gaininsight into the electrochemical sensing performance of the device design. This will allow optimizing the sensorperformance of devices to be fabricated in the future
